CAP ATTACHMENT FOR FOUNTAIN PENS.

Application led December 8; 1925.

The present invention relates to a cap attachment for fountain pens andthe like, and aims to provide a novel and improved device of thischaracter whereby the cap will be at all times carried by the pen andmay be conveniently moved and placed on either end of the pen, accordingto whether or not it. is desired-to use the pen, thus eliminating thedanger of losing the cap as often occurs with pens now on the market.

Another object of the invention is to provide a device as above outlinedcomprising a pair of bars arranged on opposite sides of and pivotallyconnected to the pen and cap, said bars having their ends that arepivotally connected to the pen arranged for sliding longitudinallythereon and having yieldable means for normally returning or holding theendsl of the bars pivoted to the pen approximately midwayl ofthe lengthof the pen, so as to yieldably hold the cap on either end of the pen.

It is also an obj ect of the invention to provide a device ofthe aboveindicated character, which is simple and substantial in construction,which can be manufactured economically, which will'not interfere withthe efficiency of the pen, and which will be thoroughly efficient andpractical in use. l

With the foregoing and'other objects in view, which will be apparent asthe description proceeds, the inventionresides in" the construction andarrangement of part-s, as hereinafter' described and claimed, it beingunderstood that changes canbe made within the scope of what is claimed,without departing from the spirit of the invention.

The invent-ion is illustrated in the accompanying drawing, wherein:

Figure 1 is an elevation of my improved pen, showing the cap in variouspositions as indicated by dotted lines,

Figure 2 is a longitudinal section taken on line 2-2 of Figure 1,

Figure 3 is a cross section taken-on line 3-3 of Figure 2, and

Figure L is a cross sect-ion tak-en on line' @-4 of Figure 2.

Referring to the drawing by numerals, the numeral designates the barrelof the pen which carries a point 11 on one end and has positionedtherein the usual ink retaining bag 12. The cap 13 for the aen has theusual spring clip 14 carried there y for yieldably holding the pen inthe pocket ofits owner when not in use.

serial No. 74,068.

In carrying out my invention, the numeral 15 indicates aipair oflongitudinal slots arranged in the barrel '10 and on opposite sidesthereof, said slots extending practically the entire length of thebarrel 10 of the. pen. Positioned in the barrel 10 and secured at theslots 15 are cylinder members 16, which are provided with reducedii.eckportioiis 17 along the longitudinal sides thereof, said neckportions having the edges thereof turned over, as at 18, for securingthe cylinder members 16 within the barrel 10. From the foregoing, itwill be noted that the cylinder members 16 are provided with a' reducedopening extending to the exterior of the barrel 10.

Arranged in each of the cylinders 16 .is a

head/or piston 19, provided'with a reduced extension 2O which extends,through theyreduced neck portion of the cylinders.y Connected to eachofthe headsor pistons 19 is one end of apair of bars 20, saidbars havingtheir ends which are connected to the heads or pistons 19 turned or bentat right angles, as at 21, and extending through openings 22 provide-dthrough the heads or pistons 19 and their reducediextensions 20. Theends of the angled portions 21'ha-ve heads 22 arranged' thereon forpreventing disengagement of the bars 20 from the heads ory pistons 19.

Arranged inthe cylinders 16 and upon both sides of both pistons ,orheads 19 are small coil springs 23, which abut against the heads orpistonsA 19v at one end and -have their opposite ends abutting againstend Y closing walls 24C provided upon the ends of the cyl-v inders. Fromthe foregoing it canA be seen that the coil springs will normally holdthe heads or pistons in positions approximately midway of the length ofAthe cylinders against tension of the springs 23.

Theopposite ends of the bars20 are also turned at rightangles, as at'25,and extend through a metallic band 26 arranged upon the cap 13, saidright angled bent portions 25 also having heads 27 thereon forpreventing dis-engagement of the bars 20 from the ring 26 and cap 13. Itwill be noted. that the bars 20 each have one end therof pivotallyconnected to the barrel of the pen while the opposite ends thereof areypivotally connected to the cap 13, so asto permit relative swingingmovement of the cap with relation to the barrel of the'l pen.

In operation, the-cap 13 may be positioned CII upon either end of thebarrel l0 of the pen. and by sliding the cap 13 away from the barrel l0until the same is beyond the end of the barrel or the point 1l of thepen and then swinging the cap to a position such as indicated by dottedlines in Figure l, the cap may be swung around and moved to the oppositeend of the barrel by exerting a pull on the cap against tension ofcertain ot the coil springs 23. As soon as th-e cap is properlypositioned at either end of the barrel l() and released, the coilsprings 23 Will move the cap upon the barrel and hold said cap in suchposition. From the foregoing, it can be seen that the cap is at alltimes carried by the barrel ot the pen, thus eliminating the 'danger otlosing the cap While changing the same from either end of the barrel.

Having thus described my invention, what claim as new is:
